Abstract (en)
[origin: EP2110974A1] The communication device (transmitter (1)) according to the present invention that constitutes a multicarrier wireless transmission system and communicates with a communication device (receiver (2)) including a function of measuring an interference-plus-noise power by using a null symbol inserted into a received data, includes a null-symbol inserting unit (12) that arranges a predetermined number of null symbols in a data-symbol storing region of a data frame to be transmitted to the receiver (2) to generate a data frame including the null symbols, thereby realizing measuring an interference power in a data transmission section with high accuracy.
